A gas fired burner is provided for use in applications such as chemical process furnaces for process heaters in refineries and chemical plants, and the like. The burner is provided with a plurality of fuel gas inlets for enabling manipulation of the flame shape and combustion characteristics of the ...

An exhaust gas stream containing oxides of nitrogen and sulfur from a fossil fuel fired boiler, a fired process heater, or a chemical process are diverted from a stack prior to emission to the atmosphere through a duct system to a mixer where an oxidant, such as ozone, is added to the exhaust gas at ...

This invention relates to low cost heat exchangers of the parallel plate-type useful for recovery or dissipation of heat energy in buildings of all types, including homes, office buildings and factories, as well as for heat recovery in the chemical process, electrical power and other industries.

The invention relates to the manufacture of manganese dioxide by a chemical process. The resulting manganese dioxide product takes the form of particles characterized by filament-like protrusions jutting out from its surface. The manganese dioxide particles having such surface features can be manufa ...

A mineral carbonation process, characterised in that the silicate feedstock is thermally activated by using heat generated from the combustion of fuel prior to reacting the activated slurry feedstock with carbon dioxide.

The invention relates to the manufacture of manganese dioxide by a chemical process. The resulting manganese dioxide product takes the form of particles characterized by filament-like protrusions jutting out from its surface. The manganese dioxide particles having such surface features can be manufa ...

The invention provides a novel process for the manufacture of biphenylcarbonitriles of the formula I as defined hereinafter which are useful for the production of certain known imidazole derivatives and certain novel quinoline derivatives which have angiotensin II inhibitory activity. The process in ...

The present invention relates generally to a new power device. More specifically, it creates hydrogen from supplied water and electricity. The hydrogen is then used in combination with air in an electrolysis-electrical cell to produce electric power. All of this is accomplished by first storing the ...

A viscosity measuring system especially useful in pollution and chemical process control applications. A variable gain amplifier drives a magnetic coil which causes a torsion member to oscillate. The amplitude of the oscillations is sensed by a transducer, and converted to a DC voltage by an amplitu ...

Oxygen is separated from air by a regenerative chemical process. Air is contacted with an oxygen acceptor comprised of a molten solution of alkali nitrite and nitrate salts at elevated temperature and pressure, causing the oxygen to react with the nitrite, and thereby increasing the proportion of ni ...
